define "broken"? NFS is used in production here for years and works like
a charm. The only annoying issue was PR 205193 (as we use jails
extensively), but it has now been fixed.

use something like:

V4: /someroot -sec=sys
/someroot/default -rw -network somehost -mask somenetmask

also, for a NFS V4 only server/client you could set:

vfs.nfsd.server_min_nfsvers=4
vfs.nfsd.server_max_nfsvers=4
